Application .lune 4, 1946, Serial No. 674,276 (c1. ass-e3) 1 Claim.

1 j The present invention relates to a toy boat made of light sheet plastic and having a propelling tubeadapted to receive a chemical which will propel the boat. Customarily, this chemical is in the form of a pellet or cartridge, and in one form the chemical produces a film which spreads outwardly from the boat, producing a surface tension on the water sufficient to propel the boat until the water is entirely covered by the film. The boat, being a toy, is customarily used on a relatively small body of water such as that in a bowl or a tub, and hence guiding means are required for causing the boat to move in a circular path. It is the specific object of this invention to so form the thin sheet hull and a sheet rudder, that the latter may be applied by a snapin action, and when thus applied will be frictionally held in any position to which it may be turned, notwithstanding the fact that the rudder is a single fiat piece of plastic.

The invention will be described with reference to theaccompanying drawings, in which:

Figure 1 is a view in side elevation, showing an embodiment of. the invention;

Figure 2 is a bottom plan view;

Figure 3 is an enlarged fragmentary vertical section through the rudder end of the hull, showing th rudder in position;

Figure 4 is a schematic view, and fragmentary showing a portion of the rudder end of the hull in bottom plan dotted lines showing adjusted positions of the rudder.

Wall and the margins Ira: of the plastic sheet material at such area are turned inwardly to form an annular holding ring.

The rudder is a died-out piece of plastic sheet, shown at 6, having a disk formation or near one end at the upper area of the rudder. Inasmuch as the inturned ring Ira: is yielding, the disk of the rudder may be pressed into the ring with a snap action, whereupon the action of the ring will frictionally grip the edges of the disk.

When the rudder is turned to an adjusted position it will be frictionally held in that position, notwithstanding the fact that the rudder is engaged by pressure only on the edges of its disklike formation. Inasmuch as the boat must be p of maximum lightness to enable the use of merely Referring to the drawings I have shown at l a v hull structure formed of aslngle sheet of plastic,

having at its top a horizontal flange la: upon which is mounted the superstructure 2, the latter being formed of a single sheet of molded plastic.

The rudder end of the hull is molded in tube formation, as shown at 3, the tube being open at its outer end so as to receive a pellet or cartridge, indicated by the dotted lines 4, which pellet or cartridge may be wholly enclosed within tube 3 or may project outwardly therefrom, the latter being indicated by the dotted lines 4.

The inner end of the tube faces a ruddercontrol cavity at 5, Fig. 3, and at the lower end or the cavity an aperture is formed in the plastic surface-tension propelling means, as for example a pellet made of aerosol, the rudder formation and arrangement is very important.

It will be understood that the specific form illustrated in the drawing may be varied without departing from the spirit of the invention.

Having described my invention, what I claim as new is as follows:

A toy boat consisting of a hull formed of light sheet plastic, the rear of the hull being formed with a tube adapted to receive a propelling'chemical, and the hull likewise being provided with an internally projected flexible plastic ring, integral with the hull structure, in combination with a rudder formed of a flat piece of plastic: having an upwardly projected disk formation adapted to snap into the ring whereby the edges of the disk will be frictionaly engaged by the ring to hold the rudder in adjusted positions.
